My invention relates to typewriting or like In'achines and moreparticularly to the line spacing mechanism thereof, and also toother-features associated with the line spacing mechanism. 7 v

I have shown my invention embodied in the presentinstanee in a Remingtonportable zi a chine, and While the various features/of the inventionhave beefi designed primarily for use in a portable hiathine, andcertain-of the features are peculiarly adapted to such a machine,nevertheless there are features of the line spacing mechanism which areer general application and are not necessarily limited to embodiment ina portable machine;

In tl'ie accempanying drawings 1 have shown only so much "oliaRemi-ngtoh portable "machineand its carrying case as is necessary to"rive at anunfd'erstanding of my. invention in its embodiment therein.

in section, ofthe line space regulating The mainframe of the machinecomprises an inner iram'e 1 which supports the various 9 i-Working partsof the machine and an outer sheet metal' frame 2 that surrounds theinner "Q. pelted oh and atta-chedto a baseboard a,

These rollers also co a ct with gui'derails *6 on the main body or base plate 7 of the springimpelledfearriage, to support the latter for traveling movement from sideto sideof the machine. The case shift frame; "of which the support 3 formspart, is'supported at its reajr 'endby Feed dogs 9 and' lO, cent-rolledin the usual 'nranner, 'co a'ct with a iteedrack 11 to control theletter teed inovementiot the carriage.

arranged at the left-hand end of the carriage, and by which the feedrack may be swung rearwardly to release it from the dog 10.

The Remington portable machine is provided with a center lock andautomatic carriage release combined with the finger wheel of the platenand its spindle so that when the finger wheel is in an expanded positionfor use, as indicated in dotted lines in Fig. 1, it will stand in thepath of a side wall Z) of the cover 0 of the carrying case and preventsaid cover from being closed. There also are provided means which compela release of the carriage from restraint of its escapement mechanism anda rendering of the center lock effective before the finger wheel of theplaten can be moved to compact position shown in full lines in Fig. 1.To recondition the machine for use, so far as the features mentioned areconcerned, it is merely. necessary to pull out the finger wheel of theplaten to the dotted line, Fig. 1, position, after the cover is removed.This results in rendering the center lock for the carriage ineffectiveand in bringing about a re-engagement of the feed rack with the feed dog10, all as will presently appear. I have embodied such features as thosereferred to above in the present construction and have combined partsthereof with the line spacing mechanism of my invention in such a mannerthat when the machine is conditioned for. transportation and forenclosure within its carrying case, as explained above, the line spacingmechanism will be automatically rendered ineffective for use. When themachine is re-conditioned for use, the line spacing mechanism willautomatically be rendered operative, as will hereinafter appear.

The main body or base plate 7 of the car riage is provided with endplates 19 and 20, each having afoot piece 19 and 20 respectively,secured by screws 18 to the base plate 7. These end plates constitutesupports for a cylindrical platen 21. Thus, the righthand end plate 19carries a bushing 22 that receives and supports one end of a spindle 23of the platen. The other end of this spindle is supported in a bushing2% secured in the left-hand end plate 20. As shown in Fig. 1, thespindle s3 is connected to the platen by a spline projection 25 on theplaten head, said projection being received in a spline groove 26 in thespindle, and by these means the platen and spindle are connected to turntogether, although the spindle may be shifted longitudinally of theplaten independently thereof.

The bushing 24 (see Fig. 5) is riveted at 9.7 over the inner side of abearing ring 28, thus firmly connecting the headed bushing 24- to theend plate 20, and firmly securing the bearing ring in place. Aplate-like line spacing pawl-carrier 29, best shown in'Fi g.

7, has a central opening by which it re ceives a bearing on the ring 28and therefore is adapted to turn on an axis concentric with the platen,which is an important factor for eliicient line spacing. This carrier 29is preferably made of sheet metal, and is formed with a laterallyprojecting arm 30 that extends inwardly across the plane of the linespacing wheel 31 secured to the platen. The arm 30 terminates in adepending ear 32 (Fig. 7) that constitutes a support for one end of apivot pin 33, the opposite end of which is secured in the body portionof the carrier 99. This pin 33 is received within the bearing portionB-l of a sheet metal line spacing pawl, designated as a whole by thereference numeral A spring 36 is coiled around the pin 33 and bears atone end against the arm of the pawl-carrier and at the other end againstthe pawl. The force of this spring is exerted to turn the line spacingpawl around its pivot 33 towards the teeth of the line spacing wheel.The pawl is formed with a hook-like engaging tooth or edge 37 which isadapted to engage the teeth of the line spacing wheel, and with anedge,.abutmcnt or stop face 38 which coacts with an undercut inclinedstop face 39 formed on the end plate 20 of the carriage, as shown inFig. 7. These stops 2-58 and 3-) co-act not only to limit the linespacing movement of the pawl and the parts connected therewith andactuated thereby, but

also prevent a disengagement of the pawl from the engaged tooth of theline spacing wheel at the end of the operating stroke of the pawl. Aspring $0 for returning the pawl carrier and the parts connectedtherewith to normal position (Fig. 2) is looped around a headed screw l1carried by the end plate 20 and bears downwardly at one free end againsta shouldered screw 42 (Fig. 5) carried by the end plate 20. The otherfree end of the spring it) bears upwardly against a pin 43 2 and '7)that is carried by an arm ll bent inwardly from the carrier 29, so thatthe pin 4:3 may be located in the plane of the body portion of saidplate-like carrier, and the spring -l0 exerts its force against thecarrier in the same plane.

As previously stated, the carrier 29 receives a bearing on the ring 28,as shown in Fig. 5, whereas the carrier bears at its outer side againstthe inner face of the end plate 20. A spacing ring a5 is supported onthe bearing ring 28 and is interposed between the inner face of thepawlcarrier 20 and the outer face of the line spacing wheel, and thepawl carrier is thus maintained against axial movement, though it isfree to turn.

Turning movement is given to the pawlarrier 29 direct from an upstandingline spacing lever 16 pivoted at its lower end outside of the end plate20 on a shouldered pivot screw 47 secured to said plate. The

. ingle movement of the hand of the operator from left to right andslightly forward, and thereby line space and return the carriage to theright at one movement. It will be observed that in thus moving from theFig. 2 to the Fig. 7 position the path of the lever 46 crosses the axisof the platen spindle 23 for purposes which will hereinafter appear.Direct and positive connection is effected between the line spacinglever 46 on the outerside of the end plate 20, and the pawl carrier 29at the inner side of saidplate, by a pin 419 carried by said leverintermediate its ends. In making such connection the pin 49 projectsfrom its lever through a segmental,

slot 20* in the end plate 20, and is received at its reduced free end ina slot 50 in the pawl carrier. It will be seen that by this constructionthe lever 46 extends practically throughout and beyond the full heightof the carriage without interference from other parts on the carriage inthe ordinary operation of the line spacing mechanism, notwithstandingthe fact that the path of the lever 46 is through the axis of theplaten. By this arrangement a long and effective leverage is provided toactuate the pawl carrier 29 and turn it around theaxis of the platenwhen the operator applies a forward pull on the finger piece 48. Suchmovement of the -.tinger piece effects a clockwise movement of the lever46 from normal position, producing an anticlockwise movement of thecarrier 29..

in order to regulate the point in the stroke of the line spacing pawlwhere it engages the line spacing wheel, andthus determine whether eachstroke shall feed the platen one or two teeth I have provided anadjustable. regulating device or shield, designated a whole by thereference numeral 51. Said device comprises ahollow knurled head 52adapted to receive a coiled expansion spring 53, which surrounds thestem of a headed shoulder screw or pin 54' secured to the end plate 20of the carriage. The head 52 is adapted to slide axially on thesupporting screw 54% and also to receive a turning adjustment thereon.The spring 53 hears at one end against the bottom wall of the opening inthe head 52 and at its other end against the head of the screw 54;exerting its force to maintain the inner end of the member 52 againstthe outer face of the end plate 20. A flange 55, formed on the This isin order to facilitate a forinner end of the head 52, is provided, asshown in Figs. 2 and 3, with two semi-circular locking notches orrecesses 56 and 57,

divided by an intermediate projection 58. The flange is also providedwith two stops 59 and 60 outside of the respective locking notches 56and 57 A locking pin 61 projects outwardly from and is fixed to the endplate 20, its axis being parallel with the axis of the pin 54. on whichthe regulating device is mounted. From an inspection of Fig. 6 it willbe seen that the pin 61 is of two diameters, as indicated at 62 and 63.The part 62 nearest the base of the pin is cylindrical, corresponding tothe full diameter of the pin, whereas the part 63 at the outer endportion of the pin is cut away nearest the member 52, formingsubstantially a semi-circular portion. As will be understood from aconsideration of Figs. 2, 3 and 6, that when the member 52 is held byits spring 53 against the outer face of the end plate 20, thecylindrical portion 62 of the locking pin will be seated in one or theother of the two notches 56, 57, depending on the position to which thehead was turned before such an engagement took place. Should theoperator desire to shift the regulater to the other position to which itmay be adjustec., it is merely necessary to pull the head out, asindicated in Fig. 6, and then turn the head until it is arrested by oneof the stops 59 or 60 co-acting with the pin 61. The head 52 is thenreleased and the spring 53 will cause the walls of the registering notch56 or 57 to engage onthe cylindrical part 62 of the pin 61 and lock thehead in its adjusted position against turning movement. The act ofpulling the de. vice 51 out to the Fig. 6 position, where its furthermovement is limited by the fully compressed spring 53 bearing againstthe head of the screw 54, brings the projection 58 between the twolocking notches in regis ter with the smaller diameter 68 of the lockingpin, thus enabling the part 5 to clear the pin 61 and permit the head tobe turned'to its newly adjusted position. The position of each of thestops 59 and 60 is such that when it co-acts with the pin 61, thecorresponding locking notch 56. or 57 will register with the part 62ofthe locking pin to effect an interlocking engagement therewith whenthe device 51 is spring pressed to engaging position. 'One side edge 64of the flange 55 of the regulating device constitutes an inclined shieldon which the engaging end 3'] of the line spacing pawl normally restsand is adapted to move, as shown in Figs. 2, 3 and 5. It will be seenthat a rotative clockwise adjustment of the regulating member 51 fromthe Fig. 2 to its other position, will cause the line spacing pawl totake up or engage a tooth of the line spacing wheel at a later point inthethrow of the pawl than when the member 51 is adjusted to the positionshown, thereby effecting a single instead of a double tooth movement ofthe line spacing wheel and platen.

A spring pressed roller detent (35 co-acts with the tooth of the linespacing wheel to insure a proper line spacing of the platen at itsactuation and to hold it against accidental displacement from suchposition.

The center lock and automatic carriage releasing means hcreinbeforereferred to will now be described, as well as the manner in which partsthereof enter into eo-operation with the line spacing mechanism. A sheetmetal controlling member (Stl is arranged on the outer side of the endplate 20, being pivoted thereto on the stem of a headed nut (57 whichco-acts with the screw 4-2, as indicated in Fig. 5. The head of the nutacting on one side of the member 56, and a spacing member in the natureoi? an arm (58 on the other side thereof hold said controlling member(36 against axial movement on its pivot. The member (36 has a recess orslot (56 therein which conforms substantially to the slot 20 in theplate 20 when the member (56 is in the normal, or Fig. 2, position. Thisis in order that thc mcmber (56 *ill not obstruct the movement of thepin 4:9 and the parts connected therewith in the line spacing operation.The controlling member 66 has a locking finger (it) that moves in across slot 70 in the bushing 24, and extends across the bore of thebushing and into the path of longitudinal movement of the spindle 2 3,as shown in Fig. 2, or clears the path of said spindle, as shown in Fig.3, depending on the position to which the member 66 is turned on itspivot. In the Fig. 2 position the locking finger (59 is in the path ofthe spindle 23 and prevents it and the finger wheel 71, secured to theright-hand end of the spindle, from being moved from the dotted to thefull line position shown in Fig. l. lVhen. however, the controllingmember 66 is shifted to the Fig. position with the aid of a finger piece72 on said member, then the finger wheel 71 may be moved to the fullline compact position shown in Fig. 1, thereby projecting the spindleacross the path of return movement of the locking finger 69. The latterwill then be at rest on the spindle 2*, preventing a return movement ofthe member 66 and the parts controlled thereby from the Fig. 3 position,although a returning spring 73, which co-acts with the member 66, istending to turn it around its pivot to the Fig. 2 position.

From an inspection of Figs. 1 and 2, it will be seen that the fingerpiece 72 for the controlling member 66, extends back in the rear of andco-operates with the carriage releasing lever 17, so that when thecontrolling member is shifted from the Fig. 2 to the Fi 3 position, andis locked in said last mentioned position, the feed rack 11 isautomatically released and held in the released position, as shown inFig. 3. This same movement of the controlling member (36 resulted inmoving a second locking finger or memb r T-l down through a slot 75 inthe base plate 7 of the carriage to ellective position. tiuch efiectiveposition is one where the locking finger 74: will co-act, during the moement of the carriage in its line of travel from either right or left toa centered position, with a second relatively fixed engaging mem her.This last mentioned member, as shown comprises a spring metal member 76secured at one end by a screw 77 to the underside of the carriagesupport 3. This member 76 has an upwardly projecting portion 78 thatextends through a slot 79 in the carriage support and has two inclinedupper edges 50 on opposite sides of a locking notch 81 in which thelocking finger 74. is adapted to be seated. l'rhen the locked-downfinger H co-acts with either inclined edge in the travel of thecarriage, the locking member 76 will be flexed down against the force ofits spring until the locking notch 8i registers with the locking finger7%. Then the reaction of the spring member it; will cause the finger tobecome seated and interlocked in the notch 81, thus locking the carriageagainst further travel in either direction. The machine, therefore, atthis time is, so tar as the parts in question are concerned, conditionedfor enclosure within its carrying case and for transportation.

To recondition the machine for use, it is merely necessary, so far asthe parts described are concerned, to pull out the finger wheel 71 tothe postion for use, shown in dotted lines in Fig. 1. This results inwithdrawing the spindle -from the path of the locking finger (it)enabling the controlling member ($6 to return to normal position, shownin Fig. 2, under the action of the spring 73, thereby releasing thecenter lock and enabling the carriage escapement mechanism to bere-engaged to control the carriage.

In addition to the foregoing it is desirable in the present constructionto automatically lock the line spacing mechanism against ei'i'ectireactuation when the machine is conditioned for transportation, asexplained above. and to automatically release the line spacing mechanismfor use when the other .t'eatur-es of the machine described areconditioned tor use. This is desirable in the present constructionbecause. it for no other reason. in the absence of such automaticcontrol of the line spacing mechanism an attempted operation thereof,when the parts are conditioned for transportation. would result ininjury to the machine. Thus in such circumstances an actuation of theline spacing handle e6 would result in the pin 49 lUU striking thecontrolling member 66',see Fig. 3, and the line spacing pawl carrierwould strike the finger piece 17 resulting in injury to the machineshouid the lever 456 be forcibly operated. The locking of the linespacing mechanism against effective opera tion at this timealso isbeneficial for another reason. Should the operator fail to observe thatthe machine has not been conditioned for useand should attempt toactuate the line spacing" lever, the operator will at once observe thatit is locked against effective operation. thus giving warning that it isnecessary to condition the machinefor use before attempting to proceedfurther with the operation of-the machine. i

Having explained the general reasons for automatically locking andunlocking the line spacing mechanism, I will now explain in detail howthis is accomplish-ed. Assume that the finger wheel 71 is moved to thecompact position, indicated in full lines in Fig. 1, and that thevarious parts are conditioned for enclosure within the carrying case andfor transportation in the manner hereinbeforc'described. The act ofmoving the finger wheel, as stated, results in moving the left.- handend ofthe platen spindle 23 out across the path of movement of a partofthe line spacing mechanism, which in the present instance is the linespacing lever 46, as shown in Figs. 1 and 3. An attempt to actuate theline spacing mechanism at this time will, after a short movement of thelever i6. bring it into contact with the projected end portion of thespindle 28, obstructing or locking' against further movement of.saidlever and the parts controlled thereby, and renderingthe linespacing mechanism ineffective. This occurs before the platen is turnedand beforeany injuryto the parts,-such as indicated above, can takeplace. The act of reconditioning the machine for use by pulline' thefinger wheel 71 out to the dotted line Fig. 1 position of use, resultsin withdrawing the left-hand end of the spindle into the bushing 24 (asshown in thus releasing the line spacing lever for such locking andunlockingand avoiding; the

necessity of a separate actuation in each instance, to effect it. V i

It will be seen. moreover. that the pawlcarrier 29 is in the nature of alever of the first order pivoted to turn around the axis of the platen,whereas thehand actuated line spacing lever 46 is in the nature of alever of the second order having direct connection with said firstmentioned lever by the pin and slot connection 49 50; and that theconstruction and arrangement of these and other parts of the linespacing mechanism are such that they are simple, compact, easy and cheapto manufacture and assemble, and highly efficient in use.

It will be seen, moreover, that the various features of my presentinvention may be readily embodied in a Remington portable machinewithout material modification of the existing structural features ofsuch machine.

In a typewriting or like machine and line spacing mechanismtherefor, of regulating means for determining the extent of line spacingmovement comprising a supporting pin, a regulating device supportedthereby and mounted to receive a limited axial as well as a pivotalmovement thereon, said device having an engaging portion with lookingrecesses therein, aspring co -operative with said device to move it toand normally nold it at the limit of its axial movement in onedirection, and a fixed locking pin of two diameters, said pin beingparallel with said supporting pin and adapted at its larger diameter toengage in one or another of said locking recesses and at its smallerdiameter to render the engaging portion of said device free to pass thelocking pin so that the device may be turned for pivotal adjustment.

27. In a typewritingor like machine and line spacing mechanism therefor,of regulating means for determining the extent of line spacing movementcomprising a supporting pin, a regulating device supported thereby andmounted to receive a limited axial as well as a pivotal movementthereon, said device having an engaging portion with locking recessestherein, a spring co-operative with said device to move it to andnormally hold it at the limit of its axial movement in one direction, afixed locking pin of two diameters, said pin being parallel with saidsupporting pin and adapted at its larger diameter to engage in one oranother of said locking recesses and at its smaller diameter to renderthe engaging portion of said device free to pass the locking pin so thatthe device may be turned for pivotal adjustment, and a shield carried bysaid regulating device and on which the line spacing pawl is adaptednormally to rest.

28. In a typewriting or like machine and line spacing mechanismtherefor, of regulating means for determining the extent of line spacingmovement comprising a supporting pin, a regulating device supportedthereby and mounted to receive a limited axial as well as a limitedpivotal movement thereon, said device having a flange with spacedsubstantially semi-circular engaging notches therein and stops forlimiting the pivotal adjustmentof said device, a spring bearing at oneend against the supporting pin and at the other end against said deviceto move the latter to the limit of its axial movement in one direction,and a fixed locking pin of two diameters the larger one substantiallycylindrical in shape at the base of the pin and the other substantiallysemi-cylindrical at the outer end portion thereof, the construction andarrangement of the parts being such that when the larger diameter of thelocking pin is seated in a locking recess said device is held againstpivotal adjustment and when said flange registers with the reduceddiameter of the locking pin, said device may receive a pivotaladjustment until one or the other of said stops coacts with the lockingpin, at which time one of the locking recesses registers with the largerdiameter ot the locking pin and will be engaged thereby by an axialreturn movement of the device under the force oi said spring.
